DETAILED DESCRIPTION OF THE EMBODIMENTS

A requirement conformity parsing method, system, electronic device and storage medium proposed by the present invention will be further described in detail below in conjunction with FIG. 1 and FIG. 2 . The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and all use imprecise scales, which are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention. In order to make the objects, features and advantages of the present invention more comprehensible, please refer to the accompanying drawings. It should be noted that the structures, proportions, sizes, etc. shown in the drawings attached to this specification are only used to match the content disclosed in the specification, for those who are familiar with this technology to understand and read, and are not used to limit the limiting condition of implementation of the present invention, so it has no technical substantive meaning, and any modification of structure, change of proportional relationship or adjustment of size shall still fall within the scope covered by the disclosed technical content of the present invention without affecting the effect and purpose of the present invention.

In view of the deficiencies in the existing requirement conformity parsing methods, in order to help the requirements analysts to review the requirements at different levels conveniently and quickly, and improves the accuracy and standardization of requirements, the present embodiment provides a software requirement conformity parsing method based on natural language processing technologies, including:

Step S1: obtaining a requirements document that needs to be parsed, and viewing a requirement;

where in the requirements document, the main traceability relationship between requirements is the refined relationship of requirements. An abstract requirement with a small amount of details that are not refined is referred to as an upper level requirement, and a specific requirement with implementation details and refined requirements is referred to as a lower level requirement. In the process of software requirements development in safety-critical fields, whether the entities described by the upper-level requirements and the lower-level requirements are consistent, and whether the behavior of entities is consistent has a huge impact on the management of requirements and the overall process of software development.

After the user introduces the requirements document that requires conformity parsing, the requirements can be displayed in a concise and intuitive way to facilitate subsequent conformity parsing operations. Since each requirements document in excel format may include multiple sheets, during the introduction process, the user is provided with the option to select a sheet. The introduced requirements document will construct a requirement structure tree, and each requirement will be displayed as a node, and the requirement structure tree used to display the requirements supports the function of quick indexing. The detailed text content of the requirement is displayed upon a click on a node. In addition to the conventional function of displaying requirements, clicking on the requirement text will invoke the stanza natural language parsing module in the tool to display the parsing results of the requirement statement model of the text. The requirement reviewer can intuitively understand the components of the requirement statement through the requirement statement model, and correct the non-standard syntax writing.

Step S2: performing requirement conformity parsing on several upper-level requirements and corresponding lower-level requirements thereof in the requirements document;

Step S2.1: establishing a conformity evaluation system for checking the consistency between the several upper-level requirements and the corresponding lower-level requirements thereof, where the consistency between the several upper-level requirements and the corresponding lower-level requirements thereof is the consistency between entities and behaviors of the entities described by the several upper-level requirements and the corresponding lower-level requirements, and a single statement and all requirements in the structure tree may be checked during requirement consistency parsing;

Step S2.2: using a natural language processing module to construct a requirement statement model from the several upper-level requirements and the corresponding several lower-level requirements, respectively, where the natural language processing module adopts the stanza natural language processing module;

Step S2.3: extracting a core content of the requirement by the requirement statement model, where the core content of the requirement includes a subject, an object, a syntactical relationship formed by subject-verb-object and a quantity relationship formed by subject-keyword-object of the requirement statement;

Step S2.4: performing syntax parsing, semantic parsing and classifier parsing respectively on the core content of the requirement through the conformity evaluation system, and giving a final evaluation result.

Several upper level requirements and corresponding lower level requirements thereof are introduced into the natural language processing module. Through the stanza natural language processing module, the requirements are firstly parsed to form a requirement statement model, and then through the requirement statement model, subject-verb-object and keyword and adverbial and other related content corresponding to the requirement are filled into the model designed one by one. Then, the model corresponding to the upper-level requirements and the lower-level requirements is parsed through syntax parsing, semantic parsing and classifier parsing, and the final results are evaluated to determine the conformity of the requirements.

Step S3: introducing a requirements knowledge map to semantically expand a proper noun in the requirements;

where the role of the requirement knowledge map is to define the relationship between two different proper nouns, which can be expanded at the semantic level to better determine the conformity between the upper-level requirements and the lower-level requirements by introducing the requirement knowledge map. After introducing the knowledge map, according to the relationship between the two defined by the user, the tool can expand it semantically, so that the parsing result can be more accurate. In addition, the knowledge map information used in the parsing process is given in the parsing results, and the rationality of the introduction of the knowledge can by determined artificially. At the same time, in order to better use the knowledge map and increase the flexibility and scalability of the knowledge map, the relevant content of the knowledge map in the requirement knowledge map interface can be directly modified, and the existing knowledge of the knowledge map can be displayed in a visual way.

Step S4: comparing requirement traceability labels of the several upper-level requirements and the corresponding lower-level requirements thereof with the structure of the requirements document, where a checking result of the requirement traceability relationship is configured to assist the requirement conformity parsing of the several upper-level requirements and the corresponding lower-level requirements thereof.

An effective requirement traceability conformity parsing method is an effective means to ensure the safety of the control system from the source. According to the requirement text information in each requirement statement and the requirement text information of the upper level requirements, when the upper level requirements described therein are incorrect or missing, the requirements should be incorrectly written. Therefore, for the introduced requirements document, the requirement traceability relationship is checked. In addition, in order to make the results of the requirement traceability relationship more intuitive, when the information in the structure is missing in the text, color red is used to mark the error; when the information in the text is missing in the structure, color blue is used to mark for reminder.

Step S5: automatically supplementing the requirements document.

The step of automatically supplementing the requirements document includes:

Step S5.1: using a machine learning model to train a historical requirements document, and to determine whether the historical requirements document needs to be added to semantic parsing according to a user feedback, where the machine learning model is any one of transformer, ngram and gpt-2; and

Step S5.2: automatically generating, after writing some requirements, a requirements document to be written according to the historical requirements document and the semantic parsing;
